I took my LR-308t to the range this week and the trigger got worse as I fired it. I couldn't measure it beyond 11 lbs 3 ozs and even bouncing the weight on the trigger wouldn't release it. I took it upon myself to modify the hammer spring while I wait for my replacement JP trigger.
Here's a pic of what I did. The pull went from well over 11 pounds with noticeable creep to 8 lbs 3 ounces with the creep imperceptible. The red lines show the location and direction of the re-formed spring. http://farm8.staticflickr.com/7032/6691047523_d3f82ed395.jpg I still plan on installing the new trigger, but I wondered if anyone has tried forming the spring like this? |

Quoted:
I ve done the bends on the right but not the one bend on the left. does seem to reduce the pull a little. but depending on what kind of ammo you are shooting, I could see light primer strikes if you do it too much Ouch! Spingineers (What I've always called people who design springs) prefer to use the term "FORM" instead of bend :-) When I was a very young field engineer working on typewriters, I once used the term "BEND" and the woman called my boss and told him I was bending all of the parts in the machine. He told me to use the word "form to factory specifications" and I never had an issue from then on. Seriously, after "forming" the spring, the pull went to ~ 1/3 of what it was from the factory. Out of the box it was completely unusable, to make matters worse when I called DPMS with the heavy trigger complaint they said basically tough luck. If I sent it back they'd send it back to me and tell me it met specifications even though they said 8 pounds is typical even though mine was well over 11. Thanks for the info, I'll watch for light primer strikes till I get the JP trigger. |
